A scientific project focused on the development of a methodology for assessing energy efficiency classes of industrial facilities identified the primary research problems. The first and most important of them is the absence of a categorical and conceptual apparatus in the field of energy efficiency in industry, both in the Russian Federation and at the global level. This fact limits the definition of the system of indicators in the diagnosis of energy consumption. The study analyzed the definitions of an industrial facility contained in the current legislative and regulatory documents, as well as related assessment categories, such as: an industrial building and an industrial enterprise. The lack of unity in the definition of the identified categories, and in some cases their contradiction, demanded clarification of the category “industrial facility” as an object of diagnostics of energy consumption in industry, within the framework of an expert survey with the involvement of Russian and foreign experts in the field of energy. The practical significance of the results of the study is that the clarification of the category “industrial facility” is an integral attribute of the process of developing a methodological framework for assessing energy efficiency in industry, affecting its substantive part.

Abstract Energy conservation is relevant to increasing efficiency in energy projects, by saving energy, by its’ rational use or by switching to other forms of energy. The goal is to secure energy supply on short and long term, while increasing efficiency. These are enforced by evaluating the companies’ energy status, by monitoring and adjusting energy consumption and organising a coherent energy management. The manufacturing process is described, starting from the state and properties of the raw material and ending with the glass drying technological processes involved. Raw materials are selected considering technological and economic criteria. Manufacturing is treated as a two-stage process, consisting of the logistic, preparation aspect of unloading, transporting, storing materials and the manufacturing process itself, by which the glass is sifted, shredded, deferrized and dried. The interest of analyzing the latter is justified by the fact that it has a big impact on the final energy consumption values, hence, in order to improve the general performance, the driers’ energy losses are to be reduced. Technological, energy and management solutions are stated to meet this problem. In the present paper, the emphasis is on the energy perspective of enhancing the overall efficiency. The case study stresses the effects of heat recovery over the efficiency of a glass drier. Audits are conducted, both before and after its’ implementation, to punctually observe the balance between the entering and exiting heat in the drying process. The reduction in fuel consumption and the increase in thermal performance and fuel usage performances reveal the importance of using all available exiting heat from processes. Technical faults, either in exploitation or in management, lead to additional expenses. Improving them is in congruence with the energy conservation concept and is in accordance with the Energy Efficiency Improvement Program for industrial facilities.

In today’s globalized world, need for competitiveness on one side and constant pressure on the reduction of negative environmental impacts on the other side, are forcing industrial companies to systematically analyse all possibilities for the optimization of their production processes. This paper presents a systematic approach for improving energy efficiency in industrial facilities. Special attention was given to activities that were necessary for the proper identification of energy saving potential and implementation of selected energy efficiency measures in the complex industrial environment. The proposed approach includes four main activities: (1) energy auditing, identification and valorisation of opportunities for improving energy efficiency, (2) identification of key personnel who needs to be trained and motivated to become involved and to make energy efficient decisions in practice, (3) implementation of selected energy efficiency measures and (4) continuous monitoring and verification of achieved results. The proposed approach has been tested in the real industrial environment and the results are confirming that significant energy savings and overall improvement of competitiveness can be reached. Additionally, special emphasis was placed on soft elements like cooperation between energy experts, process operators and maintenance staff that are crucial for the overall success.
